Don't waste time being jealous: Just pick up a bag of Quaker Masa Harina next time you pass the Mexican section of a grocery store. Dirt cheap! Here's the recipe for corn tortillas:

Any amount of masa
Water as needed to make it the consistency of smooth, soft clay

You can roll the tortillas out between wax paper, or if you are one of those OCD-types you can get a tortilla press. For the real thing, just pat them out with your hands, rotating each hand about 90 deg each pat. (Left thumb against right index finger, then left index finger against right thumb, repeat.) If this doesn't come naturally, just ask any Mexican on earth to show you how. Each one takes about 20 seconds.

Bake each until golden brown on a hot grill, frying pan, or whatever. (most authentic: cook then on a piece of scrap steel plate over hot wood coals) One flip and do the other side. Once you get it down, you can easily pat out the second batch while cooking the first, etc.

Apply a little butter and salt: Yum!
